The Windy City Rollers, Chicago’s best-known women’s roller-derby team, holds its season opener Saturday — good news for red-blooded fans who can’t wait for the baseball season to warm them up. Yet the best news is it no longer requires a trip to Cicero to see them: the Rollers are taking up residence at the UIC Pavilion, 525 S. Racine Ave. Tickets are $20 at the door, with gates opening at 5 PM for a 6 o’clock start of the bout. The Rollers are now second ranked in the nation; check out the team site here (including “Today’s Derby Dame”) or see a local WBBM Channel 2 report on them here
